Overview
Hocus-pocus is a reference to the actions of magicians, often as the stereotypical magic words spoken when bringing about some sort of change. It was once a common term for a magician, juggler, or other similar entertainers. In extended usage, the term is often used (pejoratively) to describe irrational human activities that appear to depend on magic. Examples are given below.
Examples of the extended use of the term hocus-pocus
Those relating to divination or other activity by one practitioner working in isolation: Haruspication (divination by inspection of entrails), and necromancy.
Those relating to a magical connection between two or more people: Subconscious direction, cross-dreaming, extrasensory perception, split subjectivity, telepathy, clairvoyance, channelling, psychic transcription, ‘faculty X’, ‘mind energy’.
History
The earliest known English-language work on magic, or what was then known as legerdemain (sleight of hand), was published anonymously in 1635 under the title Hocus Pocus Junior: The Anatomie of Legerdemain. Further research suggests that "Hocus Pocus" was the stage name of a well known magician of the era. This may be William Vincent, who is recorded as having been granted a license to perform magic in England in 1619. Whether he was the author of the book is unknown.
